I types of fasteners described and y/claimed by me in Letters Patent No. 839,456 and'No. 860,731, and in Ymy patentfapplication, Serial Number 385,896, In these types of fasteners., there is provided a" downwardly extending arm which passes through a slot in the tie topl and is secured/to the tie from beneath by means of a securing member or bolt, the tightening of which member firmly clamps the upper portion/ of the fastener against the rail holding;r the same in place on the tie..` lf the engagement of said secur-1 ing member, hereinafter termed the bolt, with the fastener or tie, or both, be rigid or unyieldingr, the thrust and strains exerted on the `fastener by f the rail andl set up by the passing traffic tend to' shear od theI bolt or strip the threads' from the bolt or nut. This is also true where the fastener is 'of the adjustable typeito allow shifting of the rail for regagement, causingthe angle U' between the lower armof the fastener and the tie to vary with ditterent adjustments,

so that if the bolt be unyielding the strains i thereon are not'longitudinal. In thecase of my invention, the strains on the bolt are entirely'longitudinal thereto and a-ll twist' or tendency to shear or strip is avoided.

To effect these purposes I provide a curved engagement between the bolt and the fastener arm and, preferably, between the boltand the tie. The engagement between fastener and bolt is such that the fastener may be installed or removed without taking out the bolt but by simply loosening Vthe same. I also provide means whereby th'e bolt is n'evented from turning' which would result in its loosening. I also provide means, carried by the fastener arm, which engages the hollow rib or corrufation sometimes provided in the tie toy` adjacent to the rail platform or portion-orn the tie top traversed by Specification of- Letters Patent. Appleation filed March :133,` 1908'. Serial No. 422,580.

the rail. ',By this means such corrugations are s tiened and the engagement of the fastener with the tie improved.

In the accompanying drawings, Figure l is a broken longitudinal section of a steel railway tie itted with my invention holding Aa rail in place, Fig. 2 1s a perspective of the fastener shown in Fig. l, Figz is an elevation of the bolt, washer 'and nut, Fig. 4,

is a plan View of the washer, the compara-l tive diameter of the bolt being indicated thereonin dotted lines, and `Eig. 5 is a view similar to Fig. 2 showing the'fastener with the rib enaging feature omitted. i

The fol owing1 is a "description of. the drawings. l is a box form steel tie having circumferential corrugations or hollow ribs, 2-2, on each side of tlie rail platform 3. f

4; is the rail and .f3-5 tbe fastenerslots in the tie top adjacent to each side of the'. vrail platform 3.

6-.76 are the fasteners which are shown tx) be substantially shapedand of the adjustabletype described and claimed by me in Letters Patent No. 860,731. Thus when the rail is firstl installed, one of said' fas-V teners, such as the left hand fastenerin Fig. l, engages the rail base by means of its upper engaging face, a, while the other fastener, the right hand fastener inFig. 3., engages the rail base by meansot its lower engaging face, Z). When it isv desired to shiftftherail, the fasteners are loosened and the rail moved, asto the left in Iii l, so that `when the fasteners are again tig tened, the lower engaging face, Z), of the left hand fastener engages the rail'base and the upper `engaging face, a, of the right hand fastener engages the said rail base.

The lower ari 7, of the fastener 6 extends through the slgli 5 with an upwardly curved' end portion 8, having a eoncaved upper face and a con- `veX lower face.

9is a slot,extending into said portion 8 andiis intended for engagement by the shank of the bolt l0. The bolt 10 is provided with a head having a concaved face adapted to register withthe lowerconvex face of portion 8` of the 'fastener arm 7. Said bolt extende upwardly through slot 9 in which it fits loosely and through 4lthe bolt hole 11 in the tie top, said bolt fitting loosely in said bolt hole 1l. L

12 is a loosely fitting washer adapted to tit down on the tie top and having its up per fece eoneeved at substantially the same trailie and the changed adjustment of the` fasteners with the rail, said lip llltnrns in the interior of'said rih 2 but does not become entirely disengaged therefrom. Where the fastener is to be'fused in .':onneotioinwith a tie unprovided with vthe hollon,7 ribs 2 2, the lip 14 is omitted as shown in Fig. 5. lt is evident that the character of engagement between the. bolt and the fastener arm pre rents the holt from turning and uuloosening itself. lt is also evident from the above that Whatever the angle of the fastener erin to the tie top, the holt 10 remains practically vertical as the slot 9 in the fastener arno permits the fastener to adjust itself without disturbing the bolt. l`he ein-ved, engagements of the holt enable it to swing without torsional strain or shearing tendency and thus enables the fastener to assume thrusts.A`

and other movements set up by the passing tra'flic Without fear of fracture.l The open ended slot 9 enables the fastener to beinstalled or removed Without taking out the holt which 'is a great convenience as the bolt is inserted from below, an` inconvenient process `when thetie is in place in the track. By simply loosening:r the .not lthe fastener may he installed or removed and by tightening the said nut the fastener is clamped firmly against the rail base.

l have shown, for the sake of elearness, my patented adjustable fastener, but it will loe understood that the form of engagement oet-Ween the fastener and the tie is immaterial as far as the use of my present invention is concerned. l therefore do not limit my invention to use in connection With the essere type of fastener shown but claim it in oonnection with any type of fastener having a lower arm attaehable to the tiel What I desire to claim is zl. ln rail supports, a fastener adapted to bear against the rail and a member adapted to pass hrough a` slot in said fastener and secure. the saine to the tie, the abutting p0rtions of said vfastener and said men'iher being in the forni of @Quotingrv Curves, for the purposes described.

ln rail supports, a fastener adapted to hear against the rail and haring an arm adapted to extend through an aperture in the tie and a, holt passing through a slot in the extren'iity of said arm and secured to said tie, said holt having aronnded head adaptedlo engage a reverselj,T rounded face on said arm, for the purposes]described.

3. ln rail supports, a fastener adapted io bear against the rail and having an arm adapted to extend through an aperture in the tie and a. oolt passing throu yh a slot in the extremity of said arxn an secured to said tie. the engagen'ient of the bolt with the fastener arm and with the tie heinl that ot' courting; curved surfaces, for the purposes desoribed.

l.. ln rail supports, a fastener adapted to against the rail and having an :trin uapted to extend through an aperture in the tie, means :torseeuring said arni to the tio and :i projection on said arm 1miapted to engage a roel-ss in said tio, for the purposes desrrihed.

.5. In rail supports, a fastener adapted to hear against the rail and havingan arm adapted to extend through en aperture in the tie. means for securing said arm to said tie and ay projection on said arin adapted lo engage the hollow rih ou said tie, for the purposes described.
